Specifically, it was not given the cold weather protection required, nor was it kept in a "moist" Condition to assure adecruatewater for the hydration of the cement. The concrete subcontractorr K B Concrete of Rigby Idaho, was advised of the need to providel weather protection for concrete on November 3, 1995# K B Concrete's subcontractor, who was pouring the footings for the sub3ect building, was notified of the need for cold weather protection during the later part of October. As the weather has not been terribly cold, it is probablethat the concrete in the subject foundation wa, l ill attain the design 3000 psi strength. It will, however, be necessary that your concrete sub contractor or you provide the necessary tests and documentation to substantiate the fact that the concrete has reached the required strength.. We will need copies of the concrete pickets for the trucks delivering concrete for the subject walls,verify whet her or not the concrete was regular r "'high earl " concrete. We will also need the test re u l of cork rete care or It iia=er" -tests on the concre 7te Surf ace to verify that the concrete has, in fact, ac Wired the necessary strength. The tests will need to be done by, and the test results cert i f led by a certif led concrete testiLng f im # Two local f firms do. Ing phis type of work are Forsgren Associates of Rexburg and Harper - Leavitt f Idaho Falls. Other certified concrete testing firms would, of course, also be acceptable This matter meds to be resolved as quickly as possible so it does not delay the erection of the build,ing above the foundation wall.
